The automatic high beams will occasionally fail to operate and are stuck in low beams until about 2 minutes have passed, or until the automatic high beams switch is turned off to disable the system. This seems to be a software issue, as it seems to occur when an approaching vehicle passes by with bright lights. When this happens, all high beams are disabled for a couple of minutes, even if the high beam lever is switched to low beams and back to high.

Auto high beam feature intermittently cuts out and then resumes, especially frequently in rainy weather. While off, I cannot engage the high beam without first shutting off the ahb feature. Many similar reports regarding Toyota vehicles; see https://www.rav4world.com/threads/auto-high-beam-issues.242329/

The car is inadequate in the winter. When it snows I can't keep the windows clean. They changed the fittings and I can't even put winter blades on the car. Also, and this applies to almost all new cars as well, the led lights freeze over. It's a safety hazard not to have lights that work. And it's a safety hazard to have to get out of the car in dangerous conditions to try and scrape ice off the windows and lights. The front and rear lights get caked with ice and snow. This picture is of my windshield after an hour of warming up. The wipers stay caked with ice. And when I turn them on, this is what happens. They smear the windshield with ice. They smear it with water too. I can't squeegee water with ice. I'd love to trade it in, but everyone has led lights. They're a safety hazard. And these issues are keeping me from buying a new car. I would appreciate it if you addressed these issues. The car companies won't listen to me. Thank you have a great day

Automatic high beams dim and then fail to brighten intermittently. When driving, automatic high beams function as intended then the dash indicator spontaneously turns off and the headlights fail to brighten. Vehicle has been to the dealership service department twice for this. The second time, the dealer was able to duplicate the problem both in my vehicle and in a 2019 Prius from the inventory. Toyota technical assistance is adamant that the problem is normal functionality. I fail to understand how the high beams not brightening when they should during night driving is normal functionality.
